Usage and Mechanics

These questions test your ability to correct mistakes in sentence
structure, punctuation, and grammar. For example, you might be given a
sentence like

"He garnished the salad with tomatoes,
that he grew himself in the garden."

The answer
choices will give you three different replacements for the underlined
words. Your job is to realize that the comma is incorrect. For example, you could
replace the underlined words with

..."the salad with tomatoes that he grew himself"...

You won't be tested on your memory of specific rules of grammar (you
don't need to remember the definition of "gerund" or other
grammatical terms), but you will be asked to apply the rules of
grammar in context by correcting mistakes in punctuation, grammar, and
sentence structure.
